    Which of the following for statements is(are) correct?

    (1) If a demand curve is upward-sloping,then it is a normal good

    如果需求曲線成正斜率,則該財貨是正常財(X)

    正常財必定是負斜率

    (2) If a demand curve is upward-sloping,then it may not be an inferior good

    如果需求曲線是正斜率,則該財貨可能不是劣等財(O)

    需求曲線呈現正斜率有兩種可能,其一是季芬財(劣等財),其二是炫耀財,所以說他可能不是劣等財,這個敘述是正確的。

    (3) If a demand curve is upward-sloping,then an increase in the consumer's

    income will shift the demand curve rightward

    如果需求曲線是正斜率,則消費者的所得增加將使得需求曲線往右移(X)

    分成兩個部份來討論:(1)如果該產品是季芬財(劣等財),所得增加將會使得購買量減少(左移)。(2)如果該產品是炫耀財,所得增加將會使得購買量增加(右移)

    (4) If demand curve is upward-sloping,then an increase in the price of the

    substitute of the considering goods will shift the demand curve rightward

    如果需求曲線是正斜率,該財貨的替代品價格上漲將使得需求曲線右移(O)

    不論是季芬財貨是炫耀財,替代財貨漲價將使得該產品的購買量因為替代效果而增加,同時所得效果將使得該產品的購買量增加,總效果是增加(右移)
